FCC RX mode testing with the radio_test example from nRFConnect SDK.

[VishnuPrasad V]

Hi Nordic Team,

We are using nRF-52840 + 21540 in our product.

The FCC pre-compliance test is ongoing for the device.

We are using the radio_test example to put the device in various testing modes.

In this RX_mode test, I was able to perform using both nRF devices running the radio_test examples.

When  I use one Device_A in RX mode and nRF_DK in Transmit mode using the nRF-DTM mode(nRF Desktop), the Device_A is not able to receive any packets.

In the FCC test setup, the procedure is a tester Machine will transmit data to the DUT (Device_A). and the Packet error is calculated.

Will the radio_test example be capable of Receiving data from other FCC tester setups?

or do I have to modify the code? 

Thanks!

Hello,

I have asked our FEM expert. 

It seems to be a configuration issue of radio channel. When you are using DTS sample, the both Device_A and nRF_DK needs to use same radio channel. (frequency). Without knowing the configuration of Device_A, it is difficult to know why it does not receive packets.

Could you please run the same program that is in Device_A in another nRF_DK to check if they receive packets? 

''Will the radio_test example be capable of Receiving data from other FCC tester setups?''

I am not sure about this. I will let you know later.

Thanks.

Hi Kazi,

Thanks for the response.

The frequency PAcket pattern and all is set correctly.

I think the issue is regarding the MAC_ADDRESS or Sync word between the examples not matching.

That is, the DTM example is using some other SYNC_WORD / MAC_ADDRESS compared to Radio_test.

please check if anything such is there!

Thanks!

Have you tried to run the same program on another DK?

[VishnuPrasad V]

Hi Kazi,

The same program radio_test I tried on both DK. it works.

Also if we are using nRF Connect Desktop-> DTM testing on both DK, that also works.

My requirement is can the "radio_test" example work with other standard DTM testing Setus(Like CBT testers, Bluetooth protocol DTM testers, etc.

Thanks!
